Bower镜像加速

# 01-国内bower install 慢的问题处理

# 1、问题剖析

主要是因为国内访问 GitHub 存在一些访问慢的场景，导致执行 bower install --allowed-root 时出现下载不下来或验证失败的问题。

在国内访问 GitHub 时，由于网络原因，经常会遇到速度较慢、连接不稳定等问题。尤其在使用 bower 安装包时，由于某些依赖包托管在 GitHub 上，可能会导致下载速度慢，甚至请求超时或验证失败。

# 2、解决办法

# 2.1 方法一：使用 GitHub520

GitHub520: 本项目无需安装任何程序，通过修改本地 hosts 文件，试图解决 GitHub 访问速度慢的问题 (opens new window)

提示

这种方法通过修改 hosts 文件来加速 GitHub 的访问，解决国内访问 GitHub 慢的问题。

这种方法是通过修改本地的 hosts 文件，将 GitHub 的域名指向国内的加速节点，从而提高访问速度。详细的修改步骤和配置可以参考 GitHub520 项目 (opens new window) 中的说明。

# 2.2 方法二：修改项目的 bower.json

{
  "registry": "https://registry.bower.io/",
  "strict-ssl": false,
  "analytics": false,
  "shorthand-resolver": "https://ghfast.top/https://github.com/{{owner}}/{{package}}.git",
  "directory": "app/bower_components"
}

提示

使用此方法的目的是通过代理地址来解决请求解析加速的需求。这里使用了 ghproxy 镜像站点来加速 GitHub 的资源请求。

在 bower.json 文件中配置了 shorthand-resolver，它允许我们通过代理的 GitHub 镜像站点来加速包的下载。这样可以有效解决由于 GitHub 访问速度慢而导致的安装失败问题。

扩展补充：

  • Bower 1.3.9 版本：支持使用 GitHub 的简写方式来安装特定标签或提交的包。例如，可以使用 someone/some-package 这种格式来指定 GitHub 仓库。
  • Bower 1.8.0 版本：改进了 GitHub 简写解析器，优化了简写方式的使用。默认的 GitHub 简写解析器从 git:// 改为 https://，进一步提升了简写方式的使用体验。

# 2.3 方法三：修改 bower.json 的展现方式

原始 bower.json 文件如下：

{
  "name": "adminconsole",
  "private": true,
  "dependencies": {
    "bootstrap": "3.3.7",
    "angular": "*",
    "angular-route": "*",
    "angular-bootstrap": "0.11.0",
    "underscore": "1.7.0",
    "restangular": "1.4.0",
    "angular-bootstrap-toggle-switch": "0.5.1",
    "angular-animate": "*",
    "angular-translate": "*",
    "font-awesome": "4.2.0"
  },
  "devDependencies": {
    "angular-mocks": "*",
    "commonjs": "0.2.0",
    "chai": "1.8.0",
    "mocha": "1.14.0",
    "sinon": "1.10.3"
  },
  "resolutions": {
    "angular": "1.8.x"
  }
}

通过修改 bower.json 文件，使用 ghproxy 镜像站点来加速依赖包的下载，改写后的文件如下：

{
  "name": "adminconsole",
  "private": true,
  "dependencies": {
    "bootstrap": "https://ghfast.top/https://github.com/twbs/bootstrap.git#3.3.7",
    "angular": "https://ghfast.top/https://github.com/angular/angular.js.git#*",
    "angular-route": "https://ghfast.top/https://github.com/angular/bower-angular-route.git#*",
    "angular-bootstrap": "https://ghfast.top/https://github.com/angular-ui/bootstrap-bower.git#0.11.0",
    "underscore": "https://ghfast.top/https://github.com/jashkenas/underscore.git#1.7.0",
    "restangular": "https://ghfast.top/https://github.com/mgonto/restangular.git#1.4.0",
    "angular-bootstrap-toggle-switch": "https://ghfast.top/https://github.com/yuraantonov11/angular-bootstrap-toggle-switch.git#0.5.1",
    "angular-animate": "https://ghfast.top/https://github.com/angular/bower-angular-animate.git#*",
    "angular-translate": "https://ghfast.top/https://github.com/angular-translate/bower-angular-translate.git#*",
    "font-awesome": "https://ghfast.top/https://github.com/FortAwesome/Font-Awesome.git#4.2.0"
  },
  "devDependencies": {
    "angular-mocks": "https://ghfast.top/https://github.com/angular/bower-angular-mocks.git#*",
    "commonjs": "https://ghfast.top/https://github.com/commonjs/commonjs.git#0.2.0",
    "chai": "https://ghfast.top/https://github.com/chaijs/chai.git#1.8.0",
    "mocha": "https://ghfast.top/https://github.com/mochajs/mocha.git#1.14.0",
    "sinon": "https://ghfast.top/https://github.com/sinonjs/sinon.git#1.10.3"
  },
  "resolutions": {
    "angular": "1.8.x"
  }

警告

修改 bower.json 中的所有依赖项 URL 为镜像地址，以确保国内的访问速度。

# 2.4 方法四：使用 jsDelivr 代理 GitHub

jsDelivr (opens new window) 是一个公共的 CDN 服务，支持通过代理 GitHub 存储库来加速包的下载。你可以将 bower.json 中的依赖项修改为 jsDelivr 提供的代理 URL，从而进一步提升下载速度。

例如，修改依赖项：

"bootstrap": "https://fastly.jsdelivr.net/gh/twbs/[email protected]/dist/css/bootstrap.min.css",
"angular": "https://fastly.jsdelivr.net/gh/angular/[email protected]/angular.min.js",
1
2

通过这种方式，Bower 会通过 jsDelivr 来加速 GitHub 资源的下载。

# 2.5 方法五：手动下载并使用本地资源

如果访问速度仍然不理想，可以手动下载所需的依赖包，并将它们放置到 bower_components 目录下。然后，可以通过修改 .bowerrc 文件，将 bower.json 中的路径指向本地文件夹，从而绕过网络请求，直接使用本地资源。

例如：

{
  "directory": "bower_components"
}

这种方式可以实现“秒下”，特别适合那些已经下载好依赖项的场景。
